Polymarket has acquired Dome, a Y Combinator backed startup building unified infrastructure for prediction markets, marking its first acquisition focused on developer tools.
Both companies confirmed the deal in posts on X on Feb. 19, though financial terms were not disclosed.
Dome is developing a unified API that allows developers to connect to multiple prediction market platforms through a single integration layer.
The acquisition strengthens Polymarket’s technology capabilities and reflects a broader strategy to improve developer access and expand integrations.
It also supports growth across blockchain, finance, and media platforms as prediction markets gain wider adoption among institutional and retail users globally.
Polymarket has acquired Dome 💜
We’re excited to bring our focus on speed, reliability, and dev experience to the world’s largest prediction market!
We’re committed to creating the best developer experience in prediction markets.
Building a world class experience requires world class talent…
Welcome to Polymarket, @GetDomeAPI.
Unified API
Dome was part of Y Combinator’s Fall 2025 cohort and is building a unified API designed to simplify access to fragmented prediction market infrastructure.
The system allows developers to access live and historical data through one integration rather than managing multiple connections across platforms.
This enables developers to trade, embed prediction data into applications, and deploy strategies more efficiently.
By removing technical barriers, the API supports faster product development and easier scaling for prediction market applications.
Dome raised $500,000 from Y Combinator and secured an additional $4.7 million in seed funding, according to details shared by co founder Kunal Roy.
Roy and co founder Kurush Dubash previously worked as founding engineers at Alchemy, bringing blockchain infrastructure experience.
Dubash said in a Feb. 19 post on X that Dome aimed to have the biggest impact in prediction markets and that joining Polymarket would help achieve that goal.
We’re incredibly excited to be joining Polymarket.
We’re obsessed with prediction markets and want to have the biggest impact in the space. There’s no better place to do that than @Polymarket .
We’re committed to creating the best developer experience in prediction markets.
Building a world class experience requires world class talent…
Welcome to Polymarket, @GetDomeAPI.
Infrastructure focus
Dome represents Polymarket’s first acquisition focused specifically on developer infrastructure.
The company previously acquired QCEX, a derivatives exchange and clearinghouse licensed by the US Commodity Futures Trading Commission, as part of efforts to re-enter regulated US markets.
Following approval to operate an intermediated trading platform, Polymarket expanded its partnerships and distribution channels.
The platform secured integrations with Yahoo Finance and Google Finance, extending prediction market visibility to mainstream financial audiences.
Polymarket also partnered with sports organisations, including Major League Soccer and the National Hockey League, allowing prediction markets to expand into sports-related forecasting.
Platform expansion
Polymarket has continued expanding its ecosystem through new integrations and partnerships.
Last month, the company partnered with Parcl to launch prediction markets tied to real estate trends, broadening its coverage beyond traditional event based markets.
The company also integrated with Jupiter to expand onto the Solana blockchain, improving accessibility and transaction efficiency for users operating within the Solana ecosystem.
Polymarket was recently added to the MetaMask mobile app, allowing users to access prediction markets directly through one of the most widely used crypto wallets.
Growth strategy
The acquisition reflects Polymarket’s focus on strengthening its infrastructure and expanding developer access.
Dome’s unified API simplifies how developers interact with prediction market platforms and data.
Combined with regulatory progress, partnerships, and blockchain integrations, the move supports Polymarket’s continued expansion.
It also positions the platform to scale prediction market access globally across multiple industries and technology environments.
